You guys (Stephen and Michael) have helped me a bunch over the past few years and I don't wish to dog on you in any way.

I get irritated at the manufacturers of products similar to the Powerflow who make wild claims of increased performance. They sell what amounts to a cone filter on a length of PVC pipe and charge $150 and up for it.

You have shown that actual work has been done (by you) to back up the manufacturers claims. The problem (as I see it) is that the variation of individual engines is just too huge for a blanket horsepower claim to cover. One fellow might have a stock 245HP '76 motor, one might be tricked out to the 450 HP that the CIS tops out at. Will the Powerflow give both owners 10-15HP? The data starts to scatter with all the variables each owner will have.

As you know, doing these dynos at the frequency required to reduce variabiliy in the test, and to cover all the mild to wild mods, is just too cost and time prohibitive. This is why I choose to dismiss all the "dyno wars" that fuel the HP controversy.

NOW, with all that said - I am shocked that anyone would show a decrease in power using one of these units. They should flow every bit as well as the stock mailbox. Problem is we're talking marginal increases here. You could easily lose 15 hp dynoing your car on a hot or humid day. You'd have to dyno the car randomly more than a dozen times, alternating back and forth with the powerflow, to get usable numbers. Again, cost and time prohibitive.

So where is the LTR dyno day to be held? I keep seeing it in the Potpouri but no date listed. If you've had the chance to follow my personal posts you know I've been having a lot of problems tuning my car. I'm chipping away at it when I can, but I seriously doubt she'll be running properly for a few more weeks yet. At this stage in the game I'm still not ready to pay $400 or $250 for an extra 10-15HP. I don't mind paying for asthetics (as you know) and I sure wouldn't mind trashing the mailbox.
